Hello, welcome to the thread for discussing protections for the rights of LGBT citizens in the US
This thread has some ground rules and established viewpoints under the settled laws we've previously mentioned. If you have these following questions I'm going to answer them to you now definitively, and as far as this thread is concerned there will be no more to say on the subject.
Should transgender students have rights and be protected against discrimination? Yes.
Does that include being treated as a member of the gender they identify as, and all the benefits and rights that confers? Yes.
What if it was possible to prevent a person from becoming trans by some method? We don't care.
Don't try to rules lawyer your way around that. I promise, you won't like the results.
